Understanding radioactive half life A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 11.00 µmol of the radionuclide. First, order the samples by decreasing initial radioactivity. Then calculate how long it will take for the amount of radionuclide in each sample to decrease to 1/32 of the initial amount. radionuclide sample initial radioactivity symbol half-life time for amount of radionuclide to decrease to 1/32 of initial amount 11 A 20.0 minutes (choose one) ☐ minutes 6 178 B Ta 9.0 minutes (choose one) ☐ minutes 73 194 C Os 6.0 years (choose one) ☐ years 76 64 D Ga 3.0 minutes (choose one) ☐ minutes 31 1 (highest) 2 ☑ 3 4 (lowest) 000 18 Ar
